Story of Stuff - Essay Example Leonard maintains that people are over extracting resources leading to exhaustion of certain resources that include trees and minerals. Globally, during the past decade, 30% of the planet’s resources were consumed. This was mostly done through mining and cutting of trees. To put this point across, Leonard provides statistical data showing how much the U.S is extracting and the problems that America is causing in other regions that have managed to maintain their resources (Leonard, 2007). America has less than 4% of its original forest cover remaining while 40% of their waterways have become undrinkable. Leonard stresses that this is not due to the planet’s incapacity to provide for everyone but the fact that some are using more than their share. The U.S has 5% of the world’s population but it is using at least 30% of the planet’s resources (Leonard, 2007). This implies that it is in turn creating 30% of the total waste in the world. This shows over usage o f resources, which is to blame for the disappearance of 80% of the planet’s forest cover as the developed countries exploit resources in the developing countries after exhausting theirs. In addition, the products that are being manufactured after the over-exploitation of resources are contaminated with toxins. The production stage incorporates usage of power to mix natural resources with toxic chemicals, which leads to the production of toxic products. The modern commerce uses approximately 100,000 synthetic chemicals (Leonard, 2007). However, only few of these chemicals have been tested for health related issues while none has undergone synergetic tests. A good example is the Brominated Flame Retardants, which are known to be very toxic especially to the human brain. As people dip pillows in BFR and then sleep on them for up to eight hours per night, they cannot avoid the health

Network Measurement Laboratory - Lab Report Example This experiment is aimed to experimentally determine the Thevenin and Norton equivalent circuit of a Black box network which consists of resistive elements and voltage source. Furthermore, the value of the load resistance connected across the two terminals of the black box will be determined such that maximum power is transferred from the network load. Finally, the objective of the experiment is to determine certain network parameters. This experiment will aid the students to understand the behavior of given circuits and explain their outputs, understand Thevenin and Norton principles, the principle of maximum power transfer and their implications for practical systems. Thevenin Theorem states that: â€Å"any linear terminal circuit is equivalent to an ideal voltage source Vth in series with a resistance Rth where Vth is open circuit voltage the two terminals and Rth is the ratio of open-circuit voltage to the short-circuit current (Isc) at the terminals†. On the other hand, an alternative proposition to Thevenin’s theory, Norton’s theorem states that â€Å"Any linear resistive two terminal circuit is equivalent to a parallel combination of an ideal current source In and a resistance Rn, where In is the short-circuit current at the terminals and Rn is the ratio of the open-circuit voltage to the short-circuit current†. These theorems are illustrated in the circuit below Measurements for the values of 12 VDC and 18 VDC of the excitation voltages were then made. The Thà ©venin Circuit Component was then turned over and a schematic diagram representation drawn as shown below A 10Kï â€" variable resistor was connected across the output of the black box and the current and the voltage across the resistor measured. The resistance was varied the current and voltage recorded as a function of the resistance. The current and the voltmeter measurement

Self Confidence And Leadership

Self Confidence And Leadership Purpose The purpose of this study is to test empirically whether a relationship exists between self confidence and leadership, with self efficacy as a mediator. This effect is studied with respect to gender differences among the sample population. Design/methodology/approach An online questionnaire was administered to students of XLRI, Jamshedpur. The questionnaire measured the students on various parameters like self confidence, self efficacy, and leadership quality. Gender differences were also recorded for the same. Findings There is a significant relation between self confidence and leadership of an individual, with self efficacy fully mediating this relationship. Also, it was seen that gender plays an important role in defining the leadership among management students. Research limitations/implications Only management students of a B-school were taken as sample. Also, this study administered a structured questionnaire with cross-sectional design. Future research is required on various other parameters that effect leadership quality of an individual. Practical implications The research is carried on management students. Hence, it is expected to act as a guide for organisations in determining the effectiveness of future managers with respect to co-relation between levels of self confidence and their display of leadership behaviour. Originality/value This paper studies the direct effect of self confidence and indirect effect through self efficacy on leadership quality among students of a B-school and how gender differences affects this relationship model. This model, though earlier studied in parts will now be researched upon in totality. Keywords Self confidence, Self efficacy, Leadership, Gender, XLRI, Jamshedpur, India Paper type Research Paper Introduction Leadership has become an important determinant managerial ability. Leadership has been defined as the ability to execute, organize, communicate, motivate and inspire. Several approaches have been proposed for the assessment of leadership ability. These range from specific theories of leadership, such as trait theory, to specific kinds of leadership, such as transformational leadership, to specific dimensions, such as goal setting. However, lately, the best assessment of leadership is on the ability to inspire others through positive exemplary behaviour and through empathetic communication. As such the best description of leadership ability might comprise ability to: Exercise discipline over oneself, demonstrate clarity of thought of life, and possess a well rounded worldview and philosophy on life that combines personal mastery and public interdependence in a benign, non-manipulative way. Display compassion from others point of view, and to truly empathize with others and know their motivations, concerns and preconceptions. Communicate effectively on the basis of an accurate assessment of others perspective and their various levels of drives and motivation. That is, to construct the most appropriate message, and encode and deliver it through language and otherwise in the best way possible so that the recipient has thorough understanding of the idea being communicated. Draw from ones clarity of thought powers of empathy and freedom from vanity so as to assess the situation around him accurately, and to draw a vision of a lofty but attainable future which he considers to be desirable and beneficial to the largest number of people. To inspire large numbers of people towards a common, highly meaningful and motivating goal; guiding and showing them how it is achievable, while facilitating communication at every stage To maintain utmost consideration for, and a personal bond with, the people for and with whom he is working in the process elevating them and making leaders out of them in turn. The above characteristics what a leader is supposed to achieve. However these characteristics are difficult to measure over a short period of time, so alternative methods are use. One such method has been used in this study. Organizations are constantly on the lookout for executives who display these behaviours. As such they are constantly on the lookout for methods which can help predict the leadership abilities of prospective members of the organization. Self confidence is one such measure of leadership abilities (Kaplan, 1986; Popper and Mayseless, 2007). It is considered to be one of the fundamental building blocks of leadership ability and indispensible to leadership success. A person with a high level of faith in himself or herself is likely to be a better executor and motivator. Only a high degree of self confidence can enable a person to make the effort and the choices that go into developing leadership ability. A related trait that is crucial to leadership is self efficacy. The ability to handle adverse situations by taking charge of situations has been found to be determinant of leadership in situations requiring change. This is important because ability to lead positively, empathetically and ethically while facing tough competitive situations requires a belief that one can successfully negotiate such situations without compromising. Furthermore, gender has been an area of focus in study of leadership styles. Studies have pointed out that gender is related to leadership style and performance on various leadership dimensions. Given that leadership abilities of women are expected to draw from somewhat different strengths than men, it can be expected to affect the relationship between self confidence, self efficacy and leadership. Hence we see that there is a need to study the mediating role of self-efficacy in the relationship between self confidence and leadership. Furthermore, given the significant differences found in leadership parameters of men and women, it is important to see how the strength of the relationship between self confidence and leadership abilities is affected by gender. Hence in this study, we seek to study the mediation effect of self-efficacy on the relationship between self confidence and leadership with gender as the moderating variable. Research background and hypotheses Efforts to pinpoint the influences on leadership skills have focussed, for the greater part of the twentieth century, on individual factors such as personality traits and behavioural attributes. In a 1948 literature review, over a 100 studies on trait approach were reviewed and it was found that traits like interpersonal skills, initiative, intelligence and integrity were consistent with leadership capabilities (Daft, 2005). Studies on individual traits have included research on various traits such as honesty, interpersonal skills, initiative etc. Studies have also talked about traits like self-confidence and self-efficacy in relation to leadership (Popper and Mayseless, 2007; Hautala, 2005). This study carries forward these ideas while also attempting to add to knowledge of leadership by studying factors which lead to leadership as well as the way in which other factors moderate this relationship. Self-confidence Self-confidence is a personality trait. One of the most widely accepted definitions of it comes through the Trait Theory of Leadership wherein it is considered one of the most important personality traits used to identify potential leaders (Daft, 2005). If we were to take a more contemporary definition of self-confidence, Merriam-Webster Online defines it as confidence in oneself and in ones powers and abilities. Although there is no singular definition of self-confidence as a construct, a lot of research has been done on the subject and various authors have defined it in different ways. For instance, the reasons for development of self-confidence in an individual have been identified by various authors. Self-confidence may result from a persons belief in whether he or she can performs a task a belief derived from whether or not they succeeded in performing the task in the past (Burns, 1993). On the other hand, self-confidence has also been said to develop in two phases. First, you examine whether you are capable of handling, or have adequate information about, a task and then based on this analysis you decide whether you can handle the task in the present context or situation (Koriat et al, 1980). Self-confidence has most often been linked with the concept of self-efficacy and the two terms are often used interchangeably. Apart from gaining experiential knowledge, a persons self-confidence may also increase through appropriate motivational mechanisms or through reinforcement behaviours (Bandura, 1977). The components of self-confidence have also been studied and they can be divided into internal and external components, ranging from self-love for the former to assertiveness for the latter (Lindenfield, 1995). There are also certain general behavioural indications, which have been linked to self-confidence as components or attributes, viz. a persons air of assurance and the fact that his entry or exit from a space is considered to be of note (Goleman, 1998) In an analysis of self-confidence as a concept, we can find those attributes, which are most representative of self-confidence as a stand-alone concept. These attributes include belief in positive achievements, persistence and self-awareness all of which our questionnaire attempted to capture (White, 2009). Personal characteristics such as willingness to take initiative, effectiveness, self-esteem etc. have also been variously linked to self-confidence (Kacmar and Young, 1998; Pool and Sewell, 2007). Self-confidence measures have, for the most part, continued to measure the attributes mentioned above. However, some new scales to measure it have been developed in recent years, mostly for use in specific professions. The Self-confidence Attitude Attribute Scale was developed to measure the ability of students as well as the amount of work they are willing to perform in order to succeed (Nokelainen et al, 2007). A new measure, the Perceived Self-confidence Scale was also developed for n urses in order to gauge the correlation between willingness to take up managed care and perceived self-confidence (Hayes, 2003) Self-efficacy Self-efficacy is also a construct related to personality and was first developed as part of a study on behavioural change (Bandura, 1977). It was initially defined in terms of an element which helps in development of learning abilities, especially for social or cognitive skills. The concept gained currency over the years and may now be defined as the conviction that one can act in accordance with certain predetermined norms and that such actions will lead to the successful achievement of objectives (Ormrod, 1999). It can also be defined as the belief that our actions can have a modifying effect on the environment and, hence, bring about changes or achieve goals (Steinberg, 1998). Elsewhere self-efficacy, especially among students has been examined and has been described as being capable of imagining oneself achieving a goal completely or as far as one desired to achieve it (Smalley, 1998). It has also been described as, simultaneously, an influence on and a result of socio-cultural n orms and ethnic background (Pajares, 2002). As mentioned above, a similarity of concepts has often led to self-efficacy being used interchangeably with self-confidence. This is also true in the case of efficacy, self-esteem and self-concept. Efforts to distinguish efficacy from self-efficacy have focussed on the fact that efficacy represents actual ability whereas self-efficacy represents a belief in ones ability to accomplish a goal in a designated manner (Sue et al, 2005). The sources which lead to self-efficacy as well as the factors which impact it have been divided under four broad headings learning derived from experiencing something in the past; learning from or comparing oneself with others; persuasion from social relations or even institutions and finally, our reactions to the physiological changes within us during specific situations (Bandura, 1977). Self-efficacy also has certain consequences on behaviour. For example it leads to greater effort and increased focus on ach ievement of goals (Schunk, 1990). It may also make one more competent in generating enthusiasm and motivation for a task (Gonzalez et al, 1990). On the other hand, low self-efficacy could also lead to the reverse, i.e. low competence due to lack of belief in oneself (Pajares, 2002). Self-efficacy, apart from being linked to the above-mentioned constructs (with which it is frequently interchanged), also has an impact on the way we think and act, our thought patterns and behaviour (Bandura, 1977). In order to define self-efficacy or to apply it to their research, theorists and researchers began to devise new ways to describe and measure the construct of self-efficacy. Initially self-efficacy was primarily measured on the General Self-Efficacy Scale (Scherer et al, 1982). However, more recently, apart from the universally accepted scales such as the Generalised Self-Efficacy Scale (Jerusalem and Schwarzer, 1995), other scales have been developed, such as the Scale of Perceived Social S elf-Efficacy (Betz and Smith, 2000). The latter was developed to measure self-efficacy expectations in the context of actions taken or behaviour demonstrated in social situations. There were six sub-factors to self-efficacy, in this scale, and they included performance in public situations as well as social assertiveness. These scales have also been modified according to the needs of the research (Matsushima and Shiomi, 2003). Leadership Leadership has been identified in various forms over the years. It has alternately been considered a combination of traits, of behaviours, of contingency actions etc. It can be defined as the process by which an individual encourages others, or works with others, to achieve certain shared goals (Chemers, 2002). Over time this definition has become more expansive and now includes the interrelationship between the leader and his followers. Leadership as a construct has evolved over time and this evolution can be divided into six broad types of leadership theories (Daft, 2005). The Great Man Theory of leadership defined it as inherent ability which set apart one man from the rest and he was recognised as a leader while the Trait Theory, which was in currency for nearly half a century, tried to identify those traits which can be influencers or predictors of leadership ability (Robbins, 2008). Other theories have included study of leadership behaviours, leaderships impact on followers, le adership actions to be taken in emergency, interrelationship between leadership and change etc. (Yukl, 1981). ). Leadership or leadership quality (which has been used as a construct in our survey and our research) has also been defined in terms of the people orientation and task orientation of individuals (Hemphill and Coons, 1957; Likert, 1979; Blake and Mouton, 1985). The reasons for leadership definitions being focussed on these two dimensions are the importance of both to the organisation as well as the fact that the presence of both, in an effective leader, is necessary. Irrespective of whether the two orientations are displayed simultaneously or at different situations, it is clear that extensive research has determined them to be present in successful and admired leaders (Fleishman and Harris, 1962). The various constructs which have been related to leadership over time include emotional intelligence and social intelligence (Goleman and Boyatzis, 2008), integrity and self-con fidence (Trait Theory) and other more elusive constructs such as charisma (Influence Theories). There has been a great deal of empirical evidence over the years to suggest that leadership is affected by self-confidence (Bass, 1985; Popper, 2004 etc.) and also by self-efficacy (Bandura, 1977; Paglis and Green, 2002 etc.). Various measures have been developed over the years to capture the elusive and ever-changing construct of leadership. Some of the scales developed in the last decade included the Revised Self-leadership Scale (Houghton and Neck, 2002), revisions to existing scales on Leadership Scale for Sport and Athlete Satisfaction Questionnaire (Nazarudin et al, 2009), etc. Self-confidence and Leadership From the literature which was reviewed, it was clear that self-confidence was an important part of an individuals personality and, hence, should be an important factor in the development of leadership in him. But, first it needed to be proved that personality has an effect on development of leadership or on demonstration of leadership behaviour. The study of relationship between leadership and personality has found significant interdependence between the two, with self-confidence being an important element of a leaders personality (Hautala, 2005). In one such study personality was divided into four clusters and it was proved that certain types of personality demonstrated greater leadership behaviour (Church and Waclawski, 1998). However, in order to relate the constructs of self-confidence and leadership, more research has been conducted, both empirical and conceptual. While studying transformational leadership through a survey feedback session, it was discovered that one of the important personality components, for those who scored high on leadership was self-confidence (Bass and Riggio, 2006). Similarly a study on the building-blocks of leadership development, has also shown that self-confidence was the most evident variable when it came to determining ability to lead others (Popper and Mayseless, 2007). When it comes to leadership in a business environment, there is ample research to suggest that business leadership is also dependent, to a great extent, on self-confidence. For instance, there has been research on managerial self-confidence and organisational change. The study attempts to formulate a new concept of self-confidence, which can lead to better managerial performance in terms of leading an orga nisation towards change (Bowman, 1999). The current economic environment requires a new set of business leaders with new ideas and a confident leader as well as earning confidence through respect is an important means of achieving success (Darling and Nurmi, 1995). A profiling tool on public sector managers had also discovered a lack of leadership confidence among them, which affected their ability to provide inspiration and support to subordinates and colleagues (Women in Management Review, 2007). Entrepreneurship can intuitively be considered a direct firm of leadership and studies have demonstrated that among MBA students (our sample), higher self-confidence can be statistically correlated with higher levels of entrepreneurship-orientation (Koh, 1996; Turker and Selcuk, 2009). A study on communication in groups has also shown how self-confidence is essential for improved communication (Education + Training Journal, 1960). For prospective managers it, therefore, becomes necessary to develop self-confidence as a means to developing leadership and even communication skills. Self-confidence and self-efficacy As mentioned earlier, self-confidence and self-efficacy are often used interchangeably, primarily due to the similarity of the constructs, which are both dependent on a sense of self-belief. While self-confidence is the belief in ones abilities, self-efficacy is the belief that one is capable of performing a certain task in an expected manner. Studies on either of these constructs tend to focus on the other as well. In a conceptual study on use of these constructs for therapy, self-confidence was advocated for the common man whereas self-efficacy was recommended for use in (Ulmer, 1998). The study felt that self-efficacy had more empirical support as a construct and, hence, self-confidence could be considered a sort of sub-set of self-efficacy, whereby, higher self-confidence would imply higher self-efficacy. The relationship between the two, with self-efficacy playing an important mediating role between self-confidence and effective performance, has also been empirically validated b y another study (Orpen, 1999). Not only are the two concepts interrelated but they can also be used a substitutes for each other for example self-efficacy can be seen as a private form of shoring up faith in oneself, while self-confidence can be seen as the external image we need to present to society in order to succeed It has been suggested that self-confidence can be either a trait or something that is specific to certain situations (Pool and Sewell, 2007). There have also been attempts to redefine these personality traits as contextual concepts so that it would easier to measure them and also to work towards developing them in individuals. It would also be easier to map the exact relation between the two, i.e. how the increase in one leads to increase in the other (Pool and Sewell, 2007). Most attempts at measuring one or the other have culminated in both being measured as a factor of the other. Confidence has been included as one of the six dimensions on the Occupational Self- efficacy Scale (Pethe et al, 1999). Similarly, a study on the Israeli military used the construct of self-confidence as a combination of 3 variables, one of which was self efficacy (Popper et al, 2004). Variants of the constructs have also been found to be related to each other. For example, Social Self-efficacy has been proved to have a high correlation with Social Confidence (Betz and Smith, 2000). Thus, we may say that an increase in self-confidence or high levels of self-confidence is mirrored by correspondingly high levels of self-efficacy. Self-efficacy and leadership It has been seen that high level of self efficacy makes a person better suited for leadership role than a person with a low level of self efficacy. Through the Social Learning Theory, it was demonstrated that leadership development increases with high levels of self-efficacy (Bandura, 1977). Leadership involves being committed to the organisation you work for and self-efficacy at the workplace plays an important role in increasing this commitment (Rastogi and Rathi, 2009). A construct called Leadership Self-Efficacy (LSE) was also designed and the relationship, between LSE and an increase in leadership behaviours, was empirically validated (Green and Paglis, 2002). Studies have not only related individual self-efficacy and leadership but have also shown how increase in a leaders self-efficacy, so far as it pertains to his leadership abilities and job performance, have a positive effect on self-efficacy of the team or group that is being led (Sanchez and Villanueva, 2007). Self-effica cy is also necessary for achievement of stated objectives and the construct has been found meaningful for developing better performances in an organisational setting (Appelbaum and Hare, 1996). Other research has also tried to establish a correlation between self-efficacy at work and the personal traits which can be considered essential for leadership (Schyns and Sczesny, 2010). Career success which could be defined as being able to reach a level of influential leadership is also positively affected by self-efficacy (Ballout, 2009). There has also been an interest in transformational leadership and its relation to self-efficacy for leaders, both male and female (Sanders and Schyns, 2005). For those working in expatriate roles or leading global organisations, self-efficacy has been found to be an important criterion for success (Ang and Dyne, 2006). Self-efficacy also leads to greater job involvement, a prerequisite for effective leadership (Lin et al, 2009). The ability to lead new companies or begin a new venture has been found to be positively affected by high self-efficacy (Alvarez et al, 2006). Self-confidence, self-efficacy and leadership Based on the discussion above, we can say that there is a positive relationship between self-confidence and leadership, self-confidence and self-efficacy and self-efficacy and leadership. But in order to study the relationship between self-confidence and leadership, with self-efficacy as a mediator, further research was involved. The Social Learning Theory was one of the first in establishing a correlation between these three constructs since it showed self-confidence to be an important element of self-efficacy while also establishing its relation with leadership development (Bandura, 1977). Any comprehensive study of leadership as a concept tends to include self-confidence and self-efficacy as two of the most important factors in possessing or developing leadership skills (Conger et al, 1988). Self-confidence and self-efficacy have also been found to influence the thought patterns or actions which lead to leadership development (Popper, 2004). Both self-efficacy and self-efficacy ha ve been shown to have an impact on a persons job capabilities and, hence, ultimately his leadership capabilities as well (Pool and Sewell, 2007). Self-confidence and self-efficacy have also been independently correlated to entrepreneurial leadership abilities and, considering the correlation between the two constructs, one can say that an increase in one would lead to an increase in the other and finally to an increase in leadership abilities (Turker et al, 2008; Alvarez et al, 2006). Attempts to develop future leaders have also shown that increasing self-efficacy and motivating employees to have greater self-confidence are integral to the process (Popper and Lipshitz, 1993). From empirical and theoretical research, the two constructs of self-confidence and self-efficacy have been shown to be related conceptually, since both are dependent on self-belief to a great extent. If we posit that self-confidence has a positive correlation with leadership, then an increase in one should lead to a corresponding increase in the other. However, since self-confidence is related to self-efficacy and self-efficacy is related to leadership, any increase in self-confidence will lead to increase in self-efficacy, which in turn would increase leadership ability. Genders Moderating Role on the Model The definition of gender includes the practices, beliefs and norms, internalised by men and women, with reference to their roles in society. Thus, gender influences individual decision making according to societal expectations. As a sociological entity, it also affects the development of personality and, hence, of traits such as self-confidence and self-efficacy. There has been significant research on how gender affects leadership. The possibility of women attaining leadership roles has been studied with reference to whether a glass ceiling exists and how evaluation of (and by) either gender tends to have an element of bias (Weyer, 2007). There is research to suggest that the types of roles or leadership positions offered to women are often significantly different compared to men (Lantz and Maryland, 2008). The differences in leadership orientation or style, between men and women, have also been studied to identify the varying ways in which they handle change and transformation (Yane z and Moreno, 2008). Leadership effectiveness has been analysed to show that gender differences exist (Chow, 2005). Not only does gender affect leadership but it also has an impact on various abilities and competencies which affect leadership. Studies have shown that women tend to score higher on emotional intelligence, which is generally identified with leadership (Bauch and Rucinski, 2006). There is also a significant difference in the extent to which men and women possess these success-predicting attributes (Hopkins and Bilimoria, 2008). In a study, which is of particular interest to this research, entrepreneurship skills (linked to leadership in the discussion above) were found to be influenced by levels of self-confidence. The self-confidence levels for men and women were qualitatively proved to be different, hampering women in their quest for leadership development and success. Thus, we can say that gender has an influence on the relationship between self-confidence and leader ship. Based on the discussion above, the following hypotheses are proposed: H1. Self-confidence has an impact on leadership quality. H2. Self-confidence has a positive impact on self-efficacy. H3. Self-efficacy has an impact on leadership quality. H4. Self-confidence has an impact on leadership quality by increasing self- efficacy. H5. Gender has an impact on the relationship between self-confidence and leadership quality. Research Model Self-Confidence Self Efficacy Leadership Gender Methods Sample The survey was administered to management students of XLRI of batch 2008-10 and 2009-11. There are total 420 students (294 males and 126 females), out of which 68.03% of the students chose to participate. The response consisted of 127 males and 73 females. Using stratified sampling, 102 males and 58 females were chosen using random number generator. The average age of the sample is around 25 years. The questionnaire was a self-administered questionnaire and it was sent to students using internet. Measure The constructs used here were measured using Likert and Likert-type scale with different range used for different constructs. Leadership quality It is measured using 5-point Likert type scale developed by. A sample item is The more challenging a task is, the more I enjoy it. Self confidence it is measured using 5-point Likert scale developed by Sherer et als (1982). A sample item is I avoid facing difficulties. Self efficacy it is measured on a 4-point Likert type scale using Schwarzer and Jerusalems General Perceived Self-Efficacy Scale (Schwarzer and Jerusalems, 2010). A sample item is If I am in trouble, I can usually think of a solution. Also, gender has been used as a moderator which is a dichotomous variable asking if the respondent is a male or a female. Analysis For the analysis, different methods have been used for different purposes. For measuring the reliability of various constructs the Cronbachs alpha has to be calculated for all the constructs defined in the model. For proving H1, H2 and H3 we are using linear regression model to find out the significance of relationship between the constructs of Self confidence, self-efficacy and Leadership Quality. In order to evaluate the effect of mediator we use the mediator model with multiple regression analysis or MRA which consists of four sequential steps to find out the significance of mediation and the effect of mediation. This analysis supports H4. For evaluating the effect of gender as the moderator, we first do regression analysis between the predictor and the consequent while including only the male gender in the analysis and then we do the same analysis using the female gender. This is done to find out whether gender has a significant role to play on how self-confidence affects leaders hip quality in a person. We use SPSS software to carry out our analysis. Results Reliability: In order to test the consistency of a construct, Cronbachs alpha is calculated. Following are the results for the same. According to some professionals, as rule of thumb, if value of alpha is 0.7 or higher, the construct is considered as reliable.

The Inevitable Water Shortage in America’s Future :: Drinking Water Shortage

The same dream again.   It had been haunting him for weeks now.   Always the same.   Water.   Fresh water.   Drinkable water.   He got out of bed slowly, his stillsuit itching in that one certain spot again, and went to his refrigeration unit.   What flavor do I want this morning?, he thought to himself.   Eggs Benedict.   He opened the top of the squeeze tube and gulped the yeast solution down. All the troubles had begun in the year 2010 when Aldo was in his first year of college.   The first of many droughts had hit the Southwestern United States of America due to excessive use of the Colorado River.   Few had died in that one, but it was just a child compared to the trials to come. Aldo Goldwater was now thirty-five years old.   He had grown up in Phoenix, Arizona in a time when water conservation was a thing of inconvenience.   People back then would flood their lawns, wash their vehicles, even bathe with water.   Times were different now. The Water Conservation Act of 2011 was one of the U.S. Government’s first feeble attempts to ensure water quality and availability into the future.   His father, too, had been a visionary, and was important in the drafting of that first weak attempt at revamping the water usage laws in the United States. The droughts of 2016 and 2017 proved it ineffective, however, and deaths around the country totaled in the thousands, but that was just the beginning.   As global warming and ozone layer depletion gained the forefront in the news, temperatures around the world continued to rise.   Rainfall decreased annually at a steady rate, and polar ice caps were melting, making sea levels rise.   Ironically, the US’s major source of water, the Ogallala Aquifer, the largest non-renewable reserve of water in the world (Reisner 11) ran out in 2017, just when our water situation was at its peak. Water shortages were not the only problem.   When river water is used in irrigation, much of it evaporates, the rest usually finds its way back to the river it came from.   Due to the evaporation and repeated use, it increases in salinity, salt.   Each time it is used and reintroduced into the rivers, the water gets saltier.   Each year crops got smaller, until many areas previously used for farming could no longer sustain plant life.   In some areas you could even see a white dusting of salt (Reisner 6) that looked like a frost in ninety-five degrees of heat.

They develop at different rates but all follow the same basic pattern. Physical development starts from the head, and works down the body to the arms and finally the legs. Communication develops from crying to recognizable words and then intelligent conversation. Emotionally children are reliant on their primary caregiver until they develop an awareness of themselves and are able to socialize and function independently. These various strands of development are not made in isolation or sequentially. Development is concurrent and holistic, therefore any deficiency in one area can affect the development in other areas. ————————————————- Pattern of child development Physical development | | 1. 1 a| Infant0 – 12 months| A newborn lies curled up in the fetal position, unable to raise head. Movements are instinctive such as reactions to sound or closing eyes in bright light. 3 months can turn head to look at objects. 6 months child begins to hold up head, keeping it steady for increased periods. Learns to grasp and hold objects, then moves them from one hand to the other at will. Next can pull body to a sitting position and stay upright when aided. 9 months is able to sit unaided. Releases toys by dropping. Uses pincer grip to pick up items. Holds feeding bottle. 12 months as the baby gains more body control it can roll and crawl. | | Early years1 – 3 years| The gross motor skills are developed as the child starts to stand with support. This progresses to standing alone for a couple of seconds. Can walk holding one hand for support. Can walk unaided, run and jump as she develops full control of her limbs. Finer motor skills are developed such as the pincer grip to pick up small objects. Is able to hold a spoon to feed themselves. Learns to hold a crayon to scribble and then draw shapes with. Talks well in sentences, clear enough to be understood. | | Childhood4 – 7 years| Learns to eat independently using a knife and fork. Motor skills are developed to the point where a child can walk backwards. They can now walk placing heel to toe and balance themselves on a narrow beam. Manual dexterity now allows them to catch a ball, build structures, and draw shapes. Dress and undress with assistance, then alone. Take turns in play with friends and plays cooperatively. Could be frightened of things like spiders and ghosts. Knows their left from right and how many fingers they have. | | Puberty8 – 12 years| Hormonal changes are responsible for a growth spurt at this time. Gain muscles, but can still appear to lack coordination. Develop large and fine motor skills for use in sports and hobbies. Activity increases and may want to spend more time with peers rather than parents. Noticeable body changes take place, girls develop breasts and boys’ voices change. The growth of underarm and pubic hair is normal at this time. Another indicator of this stage is the development of Acne. Pre teens begin to notice the opposite sex, but prefer to stick with their own gender. | | Adolescence13 – 16 years| Their own identity emerges in musical taste and clothes. Teenagers frequently have close friendships with their peers. Are often concerned about how they look and what others think of them. Physical changes continue as puberty is ongoing or completed. Children become more independent but still seek advice and guidance from parents. Teens are aware of the opposite sex and may be going out with them. Preoccupied by their own sexualityConflict and a lowered opinion of parents emerge as teenager tries to mature. | | Young Adult17 – 19 years| More stable emotionally. Not so concerned about body once puberty ends. Develops clear sexual identity. By the end of this stage both girls and boys will have reached physical maturity. | | Communication and intellectual development | | 1. 1 b| Infant0 – 12 months| A newborn baby cries as their only means of communication. As young babies have no concept of time, to them all needs are urgent, and should be responded to as such. Begins to formulate concepts and is aware of the physical sensation of hunger. Will cry in order to have the need for food met. Develops different cries for a variety of needs, changing, hurting, frightened or lonely. Once they find their voice they will make cooing noises and other sounds. Begins to take an interest in their surroundings, paying attention to toys. Uses voice to communicate feelings, with laughter when playing and screaming when annoyed. Can understand familiar objects and has an expectation of what they will do. Chatters away tunefully and uses voice to attract attention. Watches the actions of those around them with interest. | | Early years1 – 3 years| Will learn 2 or 3 words that will be repeated constantly. Able to make the appropriate response to simple instructions. Goes through a trial and error process to discover what an object does. Can verbally communicate what they need. Is developing an inquiring mind about things and surroundings. Uses own personal jargon with many words unintelligible to most people. Knows the names for different parts of their body. Often repeats the last word spoken by any adult in earshot. Has a growing vocabulary of over 200 words and talks to themselves continuously. Joins 2 or 3 words together to make a sentence. Can use their own name with reference to themselves. Constantly asking questions, with infantile substitution, and can relate past events to the present. | | Childhood4 – 7 years| Speech becomes more confident as the substitutions decrease and full fluent speech is achieved. Can count up to twenty using repetition. Ask for the meaning of unfamiliar words. Questioning generally is at its height. Can draw a recognizable house and detailed people. Has a sense of time and can relate to the past, present and future. Able to write their own nameCan match colours and has an understanding of numbers. Reading skills will be developing in this stage and the child might write independently. | | Puberty8 – 12 years| Speech has now developed fully. Reading and writing skills are now being refined. Able to express thoughts and discuss learning making use of language skills. Shares ideas and opinions with peer group. Speech style or jargon is important to fit in with their group. Have a fairly rigid concept of right and wrong. | | Adolescence13 – 16 years| Will confide more with their peers than their parents. Increased use of speech reduces the amount of acting out.

Peer pressure is a significant influence on them. Children want to spend more time with their friends than family. | | Young Adult17 – 19 years| As children enter adulthood they are still relatively inexperienced. The peer group losses importance and is replaced by a few close friends. Mature young adults will start to listen to their parents again, asking for advice. As a sense of identity emerges they are no longer afraid to seek counseling. One on one dating becomes important. May embark on a more intimate relationship with someone. | | Different aspects of development can affect one another | | 1. 2| Football| A child needs to be physically developed in order to play this game. They will use gross motor skills to run around and kick the ball. Hand-eye (feet-eye) coordination is also essential as the player needs to be spatially aware of where they are in relation to other things. It is no good have strong legs and great aim if you could not see where the ball was and make a connection. | | | It is not much fun playing this game in isolation. As a team game players need to have the social skills to share the ball by taking it in turns. They have to understand the cooperation factor which is vital in a competitive game. No one person can win a game on their own. | | | This game consists of rules that are available off the pitch, these may be discussed orally or read by individuals. Professional teams are supported and lively banter between children will have them routing for their side. With little instructions or intervention children can communicate with each other to organise themselves into teams and have a very good game. | Language| It is important that babies are spoken to regularly and exposed to a variety of rich language. The more they are talked to the more responsive they will be. The more that they hear, allows them to develop a larger and more varied vocabulary. Research shows that there is a link between early language and literacy skills. Increased reading and writing skills can be the foundation for academ ic and social success in the future. | | | | | ————————————————- Influences that affect children’s development Background | | 2. 1 a| Members of your family are the most important people in your child’s life. This includes siblings, aunts and uncles, cousins or even neighbours and good friends. If all is well in their world the chances are that it will be the same for your child. However things do happen that can have an effect on your child’s development and you may not realize it. If a family member becomes ill or dies this can be an emotionally upsetting time not just for the adults involved, but also for the children who have formed an attachment to them. Some less obvious influences may be the ‘expected’ birth of a sibling; the introduction of a new partner or having to move home or school. You should pay attention to any change in your child’s behaviour and check if their learning is being affected. | | Is your culture the same as the environment you are raising you child in? If not you should consider how these differences will affect your child. When English is not your first language it is helpful to your child if you encourage your child to develop this along side their mother tongue. It is important that children are able to speak, write and understand English so that they can have full access to the curriculum and make progress at the same rate as their peers. | Children are known to be a very expensive to raise and educate. Not all parents have the necessary funds to feed and cloth them adequately, let alone provide for extras. Poverty may be recognized by other children if a child does not have the latest fashion or electronic gadget at home. This may lead to a child being excluded from certain playground groups. It has been reported that children from d eprived circumstances do not usually do well aat school as this impacts on most areas of their development. | | Health | | 2. 1 b| Ill health of a mother or baby immediately after birth can have a profound effect on a child. It is in this very early stage of life that infants need the care of a constant caregiver. Any interruption to this process stops the child’s normal attachment progression. This could then result in a child struggling to form close relationships later in life. A child may be unwell occasionally and need to stay off from school for a few days. There will be cause for concern if this becomes a regular pattern. Any child who misses out on school restricts their developmental opportunities. A child who has a physical impairment is understandably restricted in certain areas, such as ovement in the playground and the social interactions that come with play. Support from adults around them is essential to help ensure they are included wherever possible. | | Growth and weight are primary indicators that are used by professionals to monitor the progress and well being of children. Children of the same age are often different shapes and sizes and there are a number of indicators that ca n explain this. For example boys are often bigger than girl, genetics may be responsible for a boy having a short stature and slight frame, or a poor diet may be responsible for a child being overweight. In all these cases reference to a growth chart may provide answers or explanation for their current development position. A pattern emerges over time for each child and cause for alarm would be if there was a sudden or sharp deviation from the normal pattern. The route for a child who was born prematurely will initially be on a lower path than that of a full term baby however it would be expected to ‘catch up’ over time. Even if this was not the case as long as the child was meeting other development goals this would not be an issue in isolation. | | | | | Environment | | 2. 1 c| Where children live has a marked effect on their social and emotional development. Children that live in a nice, clean, graffiti free, residential area are likely to grow up stress free. They will probably live in a single family residence, in a natural setting, with room to run and exercise their gross motor skills. It is likely that they will know their neighbours giving them opportunities for extended social interactions. High rise dwellings; noise and traffic pollution; overcrowding and access to services, all contribute to levels of psychological distress for many children. This manifests itself indirectly as poor interactions with parents and teachers which culminate in poor language and learning development. | | Children are routinely exposed to noise from cars, airplanes, music and other people. It is essential for children to be able to hear properly in order to learn how to read. However, when they are constantly bombarded with acute noise levels they begin to ignore all auditory input. This defense mechanism has been documented by researchers who recorded significantly reduced reading and speech ability. Children’s cognitive development is also compromised by noise pollution as adults and teachers around them struggle to be heard. Teachers can become annoyed, fatigued and impatient in a loud environment. Their teaching style can become compromised as they lose valuable time dealing with distractions. This indirectly deals another blow to the child chances of developing | | Crowding is another factor that has been noted as having a marked effect on children’s development. This phenomenon can affect the only child as well as those from large families. It comes about when a child is placed in an overcrowded situation over which they feel they have no control. Children may withdraw into themselves as a coping strategy. This may occur in a children’s activity area and result in less constructive and interactive play. Language development can be affect as parents speak less to children in crowded situations. There is also a tendency to speak in simple terms, thereby depriving them of the opportunity to hear and learn more complicated words. | | Importance of recognising and responding to concerns | | 2. | As parents you are in the best position to observe and monitor how your child is developing. Conversely when you feel that there is something wrong you should trust your instincts and don’t be afraid to discuss them with your doctor or health care professional. You might notice that your child never makes eye contact with you; perhaps they fail to respond to your voice; or they display sudden and severe mood changes sev eral times throughout the day. Instead of speculating what might be the problem might be on your own, a proper diagnosis is best. Early intervention will identify any problem and work towards solutions can start straight away if necessary. | | If you recognise that there are external issues affecting your child you should respond to them appropriately. As a parent or carer you could share your concerns with your child’s teacher. This will allow them to be alert to the child’s behaviour and they may be able to monitor their progress more closely for a time. It is also important to disclose changes in the family environment, such as a family break up with changes to living arrangements. As I have already said these may well have an effect on the child that the teacher can be forewarned to deal with. | | In some schools you may have direct access to the Special Education Needs Coordinator or the child can be referred to them via the teacher. It is always a good idea to find out from the school who these people are and what is the procedure to get access to them. If you have this information available before you need it you will be able to act quickly and correctly when concerns arise. | | ————————————————- Transitional stages Experienced by most children| | 3. 1| Being bornMilk to solidsCrawling to walkingBeing fed to feeding themselvesNappies to potty trainedUnaware to aware of selfHome to nursery| Nursery to Primary SchoolPrimary School to Senior SchoolPubertySexual awarenessChanging friendshipsHandling financesGetting a job * | | * Puberty * * You will need to watch out for Puberty, or adolescence as it is sometimes called. This is the natural transition that your child will go through on the way to becoming an adult. Aside from the growth spurt that occurs at this time for both sexes, girls will have their first period, and boys experience their first ‘wet dream’ (nighttime emission) and voice breaking etc. Less physical changes are the physiological, behavioural and relationships. The enormity of these changes may be overwhelming for a child who feels that there is something actually wrong with them but they are too afraid to ask anyone. The stress adolescents feel during these times of change can lead them to try drink or drugs as a coping strategy. Others may experiment with substance abuse or engage in risky sexual behaviour. There are various consequences that can come about from this behaviour such as contracting sexually transmitted diseases; teenage pregnancy or even death from addiction overdose or suicide * | | * These scenarios have been well studied and documented, they are included here not to alarm but to make you aware and equip you with pointers that will help you recognise situations that can be emotionally tough for your child. Stay involved with your child during these transitions and encourage them to talk to you about anything and everything, listen to them without judgment. Does your child feel neglected? Set aside some special time with them to show your interest and this will give you an opportunity to pick up on problems or changes in their behaviour. Prompt your child to talk about their experience or knowledge of different substances and the abuse of them. You have every right to know who your child is friends with and keep track of their movements. Again research has shown that children whose activities are not monitored by their parents are 4 times more likely to use drugs. Any observation of changes or disturbing behaviour should alert you to seek the help of professionals at an early stage. | | Experienced by some children | | 3. 2| A new siblingDomestic violenceBullyingEmotional abuseParents separating/divorcingSerious illness (child/parent)Family member diesUnexpected change of schoolMoving house| Physical/sexual abuseSeparation from familyParent(s) in prisonLooked after by local authorityMarriage (consensual/forced)Learn to driveGoing to universityChange group of friendsCo ming out as gay or lesbian| | * Going to University * * You might think this is great for you and your child. You have encouraged and supported them for years. They have studied hard and beat off stiff competition for a place at the university of their choice. Nevertheless, their departure is a significant milestone for the family as it ushers in a new transition and time of separation that everyone will have to get used to. Unless the family is quite wealthy the stress of financing higher education can have a negative impact on all. The adjustment for students away from home for the first time can have an effect on their mental health. The ‘empty nest’ left behind may give you as parents a feeling of loss as you relinquish some of your parental control. * The impact of university on students gives them a newfound sense of freedom as they are off the radar in terms of parental restrictions and rules. However, they will be confronted by new and different pressures as they take control of their lives. They now have to learn to live with a new ‘family’ and learn how they are now to behave with this new group of people . The opportunity for study is obviously available but so is the list of other things to do and places to go. It can be a time of sensory overload as course work and parties vie for attention. As a parent you should encourage your child to explore new interests, meet new people and discover their new surroundings, with the proviso that getting an education should be the foremost concern. Encourage them to seek out professors or other adults who can keep them focused and grounded. Ensure they know where to turn for help if they do encounter problems whether they are academic or emotional. * * In the midst of students finding their independence and doing fine – you may be in receipt of a tearful phone call. You may try to advise from a distance but this is not always possible. Work out ways to stay connected and involved by doing little things to remind them they are in your thoughts. Sending cards or notes with pictures of events they have missed can help to let them know they are loved and it is not a case of ‘out of sight out of mind’. * | | Affect of transitions on children’s behaviour and development | | 3. 3| At some time children will have to leave the comfort of their home and move on to some form of semi formal or formal education. This might initially be at a playgroup, nursery or reception class. Whichever route they take it is a time of major change for them and the way they handle it should be monitored closely. Children who have been used to one on one attention may struggle with having to share the teacher with the rest of their classmates. However those who have had a secure and happy upbringing will be emotionally mature enough to cope with the change. Children of a more delicate nature may regress in their behaviour and need reassurance to participate. They may suck their thumb for comfort or cling to a favorite toy or object. Sensitive handling of these actions will help them through and build up confidence to a point where learning is not hindered. | | Children who are looked after have been prematurely separated from parents. If this takes place in the formative years it is likely that they will have attachment issues. When this happens a child can become emotionally stuck at the age they were when the separation took place. This can then have a detrimental affect on how they view making attachments with others who are tasked with looking after them. The defense mechanism is now set to I will act up and refuse to engage with you just in case you up and leave me too. Every effort must be made to engage these special children and help them overcome their disadvantaged circumstances. Universities are well aware of the problems faced by students, especially in the first year, and have systems in place to deal with these transitions. | | ———————————————— References If you wish to do some more research or reading on the subject here are some of the books and websites I found useful when writing this booklet.

P1 web architecture and components ver2

Web architecture: Web architecture is a way of designing and planning of websites that include different areas like WWW, ISP etc. Such web architectures are discussed below. Internet Service provider: Internet Service Provider (ISP) is the organizations which provide internet services to the people and other organizations. ISP provides different software packages which includes surname, password, and access to the phones and sometimes to the TV channels. For this service their customer pays certain amount to their package.There are different organizations which provide internet service and have different features like different speed of connection to the internet. The speed of the internet connection affects the performance of the websites such as the download speed of a video clip. Web Hosting Service: Web hosting service is an internet hosting service which allows the individual and larger organizations to host their website. The website can be accessed and viewed using World Wide Web.The client pays a certain amount of money monthly to their web hosting service and these hosts provide storage capacity and different management facilities and technical support and service. These host company charges the organization or the individual by looking the static of how many users use the website per month and other various features on the web. Domain Structure: Domain name is the address of the website in the World Wide Web called IP address. This can be accessed through the internet. Such addresses are difficult to remember and might not have meaning with regards to the web page.So the owner of the website has to purchase a domain name to link to the IP address so that their website can be accessed to the internet. The domain names are kept easier so that the user can understand and remember it. A easier example of a domain name is www. Google. Com† which also owns other domain name â€Å"www. Google. Co. UK†. â€Å"WWW is the prefix and â€Å". Comâ €  is the suffix whereas the character between them is the domain name. Domain Name Registrars: Domain Name registrars are the organizations that have authority to the domain names.They provide the domain name and manage the reservation of the internet domain names. The domain name registrars on the I-J are Goddard. Com and 123-erg. Co. UK. When they offer the domain name to the weapon owner, they also claim some amount of money. The registrars have a package of certain amount of certain amount of time. Thus, the longer the mount of the time, the higher the amount of money the weapon owner has to pay to their registrars. World Wide Web: World Wide Web (WWW) is a way of accessing the information stored on the internet.It uses different types of computer languages like http to transmit information. WWW contains text, images, videos, audio and many other multimedia which can be viewed by using browser. Hardware: We can use different types of hardware which help provide internet serv ice. Such hardware includes web server, mail server, proxy server, routers etc. Web Server: Web servers stores web pages and delivers those web pages to the user by using be language http to the web browser. Web server can both be hardware and software. Any individual can turn their computer to the web server by installing the server software.Each server has limited capacity so the website which is hugely us all over the world has multiple web servers. Mail Server: Mail server is a computer server which consists of storage area where email for local users is stored. This server sends and receives emails. This type of server only controls the email traffic on the internet. Proxy Server: Proxy server is a server which shares the internet connection and other services. It is like a web browser which is in between the user and the web server. It can sometimes improve the performance for the users and filters the requests by the user.It is mostly used on the business organizations and co lleges. It is to prevent the students and the staffs' access from specific web sites during the official hour. Router: A router is a device that is connected to two or more networks. Router forwards the data packets along to the different networks. Once the packet is sent from the computer to the router it forwards to the different router till the packet is received by the final device. Router maintains the movement of the packet in the internet while transferring the packet between the user and the server.Software: There are various types of software which links the computer to the internet and other networks. Browser is one of them which locates and displays the content on the World Wide Web. There are various kinds of browser such as Google chrome, Safari, Firebox, Internet Explorer used to surf the internet and web pages. These are the famous and leading browser in the world. Some browsers are preinstall on the new computers while the other browsers can be downloaded from the in ternet on ere of cost. Email is the other software which is used to receive and send the emails from the email server.The user has their own activated account through which they can send various messages like text, video and pictures. Protocols: Transport and addressing egg TCP/IP Application layer HTTP, HTTPS, ESMTP Web Functionality Web 2. 0: Web 2. 0 is the second generation of the www. It is focused on the ability for people to collaborate and share information online. It keeps static web pages that don't change. It has richer content/broadband. Went 2. 0 refers to the transition from tactic HTML web pages to more dynamic web that is more organized and is based on serving web application to the users.Dynamic website contains web pages that are generated dynamically. Each time the user access to the web page, the HTML is generated in real time and is sent to the user's browser. For example: Amazon is a dynamic website. When the user gets access to it, the page displays the types of products which might make interest the user by analyzing the users' purchase history. The site generates the weapon differently to the different users. Blobs: Blob is a personal web page on which the user records and posts their thoughts and pinions, their research and hypothesis principal etc. N a regular basis. The other users can reply to their comments. The blobs are used to share information on the internet. Nowadays the user can use more features and function as compared to the start days of the blob. The blobs are kept up to date so that the information shared is accurate and reliable. Online Application: Online application has changed in recent years. Microsoft office used for home and office purpose now is being used as an online version of word office 365. People can access to the online version and use the word.It is cheaper than to buy the whole software package and easy to access via internet. When there is no internet connection the online version cannot be used. Ad ditionally, online versions don't have many features than the Microsoft Home office. Other examples include games hosting online accessing via internet (online games) and emails. Cloud Computing: Cloud computing is an internet based computing in which different service like servers and storage and application are transferred to an organizations' computer system via internet. It has an ability to run an application on many connected at the same time.
